Basic and quality knowledge of enamelled wire
The concept of enameled wire: Definition of enameled wire: it is a wire coated with paint film insulation (layer) on the conductor, because it is often wound into a coil in use, also known as winding wire. Enamelled wire principle: It mainly realizes the conversion of electromagnetic energy in el...Read more -
Annealing process of enamelled wire
The purpose of annealing is to make the conductor due to the mold tensile process due to lattice changes and hardening of the wire through a certain temperature heating, so that the molecular lattice rearrangement after the recovery of the process requirements of the softness, at the same time to...Read more -
Diameter change of enamelled copper wire to enamelled aluminum wire
The linear diameter changes as follows: 1. The resistivity of copper is 0.017241, and that of aluminum is 0.028264 (both are national standard data, the actual value is better). Therefore, if converted completely according to the resistance, the diameter of aluminum wire is equal to the diameter ...Read more -
Advantages of enamelled flat wire over enamelled round wire
The section shape of common enameled wire is mostly round. However, the round enamelled wire has the disadvantage of low slot full rate after winding, that is, low space utilization rate after winding. This greatly limits the effectiveness of the corresponding electrical components. Generally, af...Read more
